Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a retractable roof characterized by the shape and combination of a movable roof constituting a retractable dome roof.

<< Prior Art >> Conventional open / close type dome roofs include a vertical movement type, a horizontal movement type, and a rotation movement type, depending on the movement means and movement direction of the roof.

In the vertical movement type, the moving roof moves up and down toward the opening. Further, in the horizontally movable type, the movable roof horizontally moves to open and close the opening, and in the rotary movable type, the movable roof rotates around the opening to open the opening.

<< Problems to be Solved by the Invention >> The horizontally movable type requires an area for receiving the movable roof in the moving direction, and the vertically movable type tends to have a large moving power capacity. Further, although the rotational movement type is advantageous in these points, the support structure is unstable.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a retractable roof having a high opening ratio while stabilizing a supporting structure of a moving roof.

<< Means for Solving the Problem >> In order to achieve the above object, the retractable roof of the present invention has four strings each of which is provided to the girder with a step on the peripheral portion of the planar circular retractable dome roof. A crescent-shaped roof is constructed, one of which is a fixed roof, and the other three are sequentially laminated and have a level difference, and swivel along the peripheral part under the fixed roof. The moving roof has a rectangular opening formed in the center and is closed by a moving roof movably supported by guide tracks laid along at least two parallel axes extending from the moving roof to the fixed roof. It consists.

<Operation> The crescent-shaped moving roof is supported on the periphery of the dome roof at the periphery, and the parallel-moving roof is supported by two or more parallel guide tracks connected to the crescent-shaped moving roof and the fixed roof. , Both are stable, and the translating roof first moves on the fixed roof.

At that time, the center of gravity of the translation roof moves to the fixed roof, and the entire translation roof is supported by the track on the fixed roof, that is, the fixed roof. Therefore, at this time, the support of the parallel moving roof by the track laid on the crescent-shaped moving roof may be released.

The remaining three crescent-shaped movable roofs, which are located at the top, middle, and bottom, are swung below the fixed roof along the peripheral locus of the dome roof.

Since all of these support the peripheral portion at the peripheral portion of the dome roof, they are simultaneously swung and moved to quickly open the roof.

The opposite movement occurs when closing the opening in the dome roof.

<Examples> Hereinafter, preferred examples of the present invention will be described in detail with reference to the drawings.

Figure 1 shows the four crescent shaped roofs in the closed position,
A crescent-shaped fixed roof 2 integrated with a circular outer wall 1 is arranged on the left side, and a crescent-shaped moving roof 7 is defined on the upper and lower sides and on the right side by the beams 3, 4 and 5, which are strings passed to the outer wall 1. , 8,9 are arranged.

The upper edge of the outer wall 1 has a level difference that gradually decreases from the outer diameter to the inner diameter in three steps, upper and middle lower, and the beam 3 that constitutes the upper movable roof 6 in FIG. The beam 4 on the right side is passed to the middle stage, and the beam 5 on the lower side is passed to the lower stage to form an upper moving roof 6, a middle moving roof 7, and a lower moving roof 8, respectively.

The outer peripheral edges of the moving roofs 6, 7, 8 are on the upper edge of the outer wall 1, the rail 9 of the moving roof 6 is on the upper stage, the rail 10 of the moving roof 7 is on the middle stage, and the moving roof is on the lower stage. 8 rails
11 are laid and these are supported so that they can run freely.
That is, each crescent-shaped moving roof 6,7,8 is supported by the beams 3,4,5 and rails 9,10,11.

With the above configuration, the top surface surrounding the outer wall 1 is covered with four crescent-shaped roofs consisting of the fixed roof 2 and the moving roofs 6,7,8, but a square opening is formed in the center. Remain. As shown in FIG. 2, this opening is closed by a parallel moving roof 12 formed in a quadrangle.

The parallel moving roof 12 is a parallel moving roof 12 on the surface of the fixed roof 2.
Rails on a fixed roof that were passed in parallel at a distance close to the width of the
13 and the upper moving roof 6 along the extension axis of this rail 13
And rails 14 laid on the surfaces of the lower moving roof 8 and the lower movable roof 8 are supported by carriages 15 arranged at the respective right ends.

That is, the parallel roof 12 has four corners at which the carriages 15-15
It is stably supported by -15-15.

In addition, a parallel moving roof is provided on the edge of the fixed roof 2 that becomes the chord.
A roller 16 for supporting the back surface of 12 is projected, and when the parallel moving roof 12 has moved all the way onto the fixed roof 2, it carries the right end edge thereof and is mounted on the rail 14 on the moving roofs 6 and 8. Dolly 1
5,15 can be released from the rail 14. This is because the entire roof has a dome shape,
Is moving toward the fixed roof 2 The carriage 1 on the moving roofs 6 and 8
Since 5 and 15 are lifted from the rail 14, they are naturally released. With this, the stability of the parallel moving roof 12 is secured by the roller 16.

When opening the roof, first the translating roof 12 moves onto the fixed roof, and then each moving roof 6,7,8 sequentially or simultaneously or from any one depending on the circumstances such as sunlight or the circumstances of the event. Move on rails 9, 10 and 11 under 2. In this way, the opening 17 is obtained on the top surface of the outer wall 1 as shown in FIG.

When closing the opening 17, the opening and closing operation procedure is reversed.

<Effect> As described above in detail, according to the retractable roof of the present invention, the outer edge of the crescent-shaped fixed roof and the other two crescent-shaped moving roofs are along the edge of the dome roof. Since the string does not pass through the center apex, the height is low and both ends intersect with the other roof edges, so The effect is to obtain an extremely stable support structure while reducing the surface that receives wind resistance.

Also, the strings of the crescent-shaped roof are four strings that are passed to the girder with a step on the periphery of the dome roof, so the crescent-shaped moving roof with a short axis extending to the center point of the extremely thin curvature. Therefore, not only is it stable by supporting only the peripheral portion, but also the aperture ratio is increased, and since each moving roof is curved, there is a favorable acoustical effect in terms of equalizing the sound pressure level.
